Abstract
A method is presented to draw rectangles to represent categorical data rela tionships. The idea is an adaptation of a scaled Venn diagram. Rectangles a re drawn with area proportional to the frequency of categories and the rect angles are positioned to overlap each other so that the areas of overlap ar e in proportion to the joint frequencies of the characteristics. The diagra ms are especially useful to illustrate symptom co-occurrence. Copyright (C) 2001 John Wiley & Sons, Ltd.
